How to solve the mine cart puzzles in Honkai Star Rail


There are plenty of puzzling side missions for you to take on in Honkai: Star Rail. On Jarilo-VI, you can speak with Antonia in Boulder Town to help her solve some mine cart conundrums. It’s a three day side mission with nine separate puzzles to solve. Think you’re up for the challenge? If you find that you need a little help, we’ve got you covered. Here’s a complete Night on the Great Mine Side Mission Guide.

Honkai Star Rail Night on the Great Mine Walkthrough

To start these quests, you’ll need to speak to Antonia who is standing by the World Shop in Boulder town. Select “I heard you are looking for me” as a dialogue option, and she will direct you to the Great Mine.

Follow the blue diamond to the Senior Mine Cart Operator in the top right corner of the Great Mine map. He’s instructing an apprentice on how to properly operate the mine carts. Verbal instructions aren’t going well, though, and the Senior believes the best option is a physical demonstration.

To solve these puzzles, you’ll need to push loaded and unloaded mine carts to their designated destinations. Unloaded carts need to be parked at blue Stop Points. Loaded carts need to be parked at yellow Stop Points.

When pushed, carts will follow a split in the track that is marked with a yellow highlight. To change which track is “open”, interact with the switches nearby each split. Carts will not pass through a split into a single track if the split they are on is not highlighted. This will come back up in Puzzle 7!

At times, you may have to load an empty mine cart with ores. This can be done at the stops that are surrounded by Geomarrow Ores.

The puzzles will increase in difficulty as you progress. Much like the Sensitive Beings side mission, You’ll be able to solve three puzzles initially, but then must wait a full day to solve the next set of three. A final set of three will unlock on the third day.

The final puzzle on the second day looks harder than it is. Because the puzzle ends with two loaded mine carts, were going to start referring to them by letters.

Kepp working with Mine Cart B, pushing it around the Puzzle to Stop Points 3, then, 1, then 2. Finally, you can Push Mine Cart A into position at Stop Point 3.

The Third Day’s Three Mine Cart Puzzle Solutions in Honkai Star Rail

These last three puzzles pose the greatest challenge. I had to get a bit creative to solve them.

It appears as if there is no Stop Point to use to allow the mine carts to pass each other. So, I used the split in the track to my advantage, and created Stop Point 2 at the first split by pushing the Empty Mine Cart (B) into the split along the path that wasn’t highlighted. To finish out the puzzle, push Mine Cart A to Stop Points 3, then 4. Finally, open the Track to push Mine Cart B to Stop Point 1, load the cart, then push it into Stop Point 3.

Here again for the second puzzle it appears as if there are not enough Stop Points for all three mine carts. There are, you’ll just need to a bit of switching. Start by pushing Mine Cart A to Stop Point 2, then Push Mine Cart B to Stop Point 1. To set up, your last move will be to push Mine Cart C into Stop Points 1, then 4.

Next you’ll be putting them all back in their places in order. Work on Mine Cart B (the empty one) first, by Pushing it to Stop Points 3, then Five. Next push Mine Cart C from Stop Point 4 to 3. Finally, push Mine Cart A back into place from Stop Point 2 back to 1.

The final puzzle made me think outside the box the most. It took a few minutes to realize that I could push the mine carts into each other as a solution.

Star by pushing the Loaded Mine Cart (C) into Mine Cart B at Stop Point 3, then into Mine Cart A at Stop Point 1, and finally out of the way into Stop Point 2.

Next you’ll want to push Mine Cart B to Stop Point 4 out of the way. You can now push Mine Cart A to Stop Points 3, then 5, load it full of Geomarrow, then Push it back to Stop Points 3, then 1.

The puzzle solves itself at this point. Push Mine Cart B back to Stop Point 3, then 5. Load it with Geomarrow and send it back to Stop Point 3 to solve the puzzle.
